Then the Jews retorted, “What sign (attesting miracle) can You show us as [proof of] your authority for doing these things?”
Jesus answered them, “Destroy this temple, and in three days I will raise it up.” So “when He had risen from the dead, His disciples remembered what He had said”.
And “they believed and trusted in and relied on the Scripture and the words that Jesus had spoken” (John 2:18-19, 22 AMP)
There is power in spoken words!….our words have the capacity to birth manifestations!.
Jesus spoke what was to come, and by the words of His mouth indeed the real temple (His body) was destroyed and rebuilt in 3days).
